About putting back Firebird experimental

Hello,

Considering the number of bugs about Firebird migration (see 
https://bugs.documentfoundation.org/show_bug.cgi?id=116968) and the fact that these bugs may not be 
trivial to fix (see 
https://wastack.wordpress.com/2018/07/25/database-migration-in-libreoffice-bug-fixes-and-more/), 
thought it could be relevant to put Firebird back to experimental or at least stop to propose 
Firebird migration when opening an odb file with hsqldb embedded.

Remark: don't misunderstand me, I'd enjoy to replace HSQLDB to help to remove Java dependency. 
Also, I know that HSQLDB upgrade has been delayed/cancelled because we had plan to replace it by 
Firebird but let's face it, I don't think we're ready to propose Firebird widely.
Let's not forget there are too few dev experts working on Base part (Lionel + Tamás + Jean-Pierre 
Ledure for specific Access part).
(I'm trying sometimes to work on Base part but most of bugs are too difficult for me and require a 
good understanding of Base mechanisms).

Now perhaps I'm too pessimistic here, so would like your opinion.

Any thoughts?

Regards,

Julien
